LAMP-FILLING CAN.

SPECIFICATION forming part of Letters Patent No. 363,737, dated May 24, 1887.

Application filed March 9, 1887. Serial No. 230,227. (No model.)

To all whom it 12mg concern.

Be it known that 1, JAMES H. FRANKLIN, of Sandusky, in the county of Erie and State of Ohio, have invented a new and Improved- LampFilling Can, of which the following is a full, clear, and exact description.

My invention relates to an improved can for filling lamps, and has for its object to provide a can adapted to contain what is known as coal oil and other lightinflammablehydrocarbon oils, wherein a lamp or other receptaole may be filled with the fluid without the inconvenience of lifting the can or the liability of spilling the oil over the outside of the lamp or over the floor, carpet, or furniture.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side elevation of a can partly broken away, and Fig. 2 is a partial central and vertical section through the same.

The can or vessel A, which in the drawings is illustrated as having a more or less conical top, a, and suitable bail and ears, I) b, is provided with an upper and central aperture, B, surrounded by a threaded collar, 13, integral with said conical top, the said collar being adapted to receive a threaded cap, C, whereby a gas-tight joint is effected. The cap O isprovided with a central aperture, in which a thimble, D, is inserted. The said thirnble, having preferably inclined sides, projects downward within the said cap, being rigidly secured thereto by soldering, brazing, or other equivalent means.

A flexible air-bulb, E, is provided, having a tubular shank, E, the sides of which are made to taper in corresponding manner to the inner surface of the thimble D. The tapering shank E is adapted for detachable insertion in the said thimble, as shown in Fig. 2, the contact being so effected as to form an air-tight joint. The air-bulb E is provided with two check-valves, d and d, the upper valve, (1, acting in the capacity of an air-receiver and the lower valve, (1', as a discharge.

A pipe, F, is entered at one side of the can to extend vertically downward to the bottom, where a series of apertures, e, are provided in the pipe, as shown in Fig. 1. Above the point of attachment of the pipe to the can-body, l which attachment is gasproof, the said pipe is made to curve outward, as illustrated. at f, and below said curve, outside the can, a stopcock, f, is inserted in said pipe F. As a means for insuring the perpendicularity of the pipe, a brace, c, is attached to the pipe and to the body of the can.

A rubber tube, F, is made to encompass the curved end f of the supply-pipe F, the said able, contact by a ring, G, which ring, being made of a diameter about equal to the normal diameter of the tube, firmly binds the same to the pipe when slid over the connection, as illustrated. The rubbertube F, which may be of any desired length, is provided at the end with an aperture or apertures, g.

The operation isas follows: The can having been filled with fluid, the free end of the tube F is introduced into a lamp or other receptacle to be filled, which lamp or receptacle may be above the can, and the air-bulb E is compressed by the hand, whereupon the fluid is forced, through the action of the valves (Z d, from said can into the lamp without spilling or soiling the hands.

The outward flow of the contents of the can can be stopped instantly by raising the shank of the bulb out of the thimble of the cap, so as to allow the escape of air from the can through the said thimble, whereby any outward flow or drip after the lamp has been filled is prevented.

It will be observed that the check-valve with which the air-bulb is provided renders it airtight, and also that the stop-cock f renders the can air-tight, whereby evaporation of the fluid is obviated. Thus by opening the stopcockf and compressing the bulb E the fluid may be caused to flow into any desired receptacle, and by closing the stopcock f evapora tion is prevented.

I am aware that it is old to force oil from a can into a lamp by means of air forced into the can, and I therefore do not claim such invention.

tube and pipe being held in close, yet detach ing in the top of the can, having a tapering and inwardly-projecting thimble, D, and the air-bulb E, having a tubular shank, E, fitting in the thimble of the cap, substantially as herein shown and described.

JAMES H. FRANKLIN.
